Kotlin Algorithms and Design Patterns

This repository lists the most common algorithms, data structures, and design patterns written in the Kotlin programming language.

All code is divided into separate packages:

1. sorting - sorting algorithms
2. search - search algorithms
3. structures - data structure (lists, arrays, stack, queue, binary trees, e.t.c)
4. design-patterns - design patterns
5. other - other algorithms (Levenshtein distance, Knut Morris Pratt algorithm, e.t.c)

For each code file, tests are made, which are located in the test/kotlin directory

Also, whenever possible, I add javadoc for each class, method, and file
